The one you have is correct for the DZ; it's the Crane blueprint version of the original "30-30" cam, made for GM Performance Parts (Crane makes all the GMPP cams).

ok perfect, we have the motor in the basement complete just needs to be assembled, but i wanted to make sure that this is a close as possible to the original camshaft, so i was just double checking.
